The ''other'' Creator/JimmyStewart Christmas movie--and it's every bit as good as [[Film/ItsAWonderfulLife the one you're thinking about]].

A classic 1940 RomanticComedy from legendary director Creator/ErnstLubitsch, starring Stewart and Margaret Sullavan as bickering department store co-workers who are also ([[ObliviousToLove unbeknownst to them]]) pen pals in love. Set in Budapest, Hungary, since it was based on the play ''Parfumerie'' by Hungarian author Miklós László.

Remade in 1949 as ''In The Good Old Summertime'', a {{Musical}} version starring Creator/JudyGarland and set in Chicago in TheGayNineties. Adapted as TheMusical ''Theatre/SheLovesMe'' on Broadway in 1963. Remade again in 1998 as ''Film/YouveGotMail'' with Creator/TomHanks and MegRyan, with that newfangled technology like ''email'' and ''instant messaging''.

!!This film features examples of:
* BelligerentSexualTension: Between the two leads.
* BrutalHonesty:
-->'''Miss Novak''': Mr. Kralik, I don't like you.
* ButHeSoundsHandsome:
** Subverted. Kralik pretends that he met Miss Novak's "Dear Friend," and ''insults him.'' before TheReveal. She admits then she'd long hoped it would be him.
** Played straight earlier in the film, when Miss Novak receives a letter from the "Dear Friend", who says he saw her with Mr. Kralik at the restaurant. "Who is this very attractive young man? He's just the type women fall for."
* TheComicallySerious: A Lubitsch trademark, in that everyone in the film is this, except for Vadas (who isn't actually funny but who wears a perpetual smirk.) Critic David Thomson notes that Kralik and Miss Novak in particular are almost entirely humourless, which just makes them funnier.
* ContrivedCoincidence: Where does Klara find a job in Budapest? The store where her anonymous pen pal works.
** To be fair, although the shop just happens to be where her correspondent works, Kralik makes a special effort to persuade her that they don't have an opening, and it's only when she demonstrates her awesome powers as a sales clerk that Matuschek yields and hires her.
* DatingServiceDisaster: Two anonymous pen pals fall in love with each other, then meet in real life (without realising that they're pen pals) and hate each other.
* DramaticIrony: From the point Kralik knows who his "Dear Friend" is, and Miss Novak doesn't.
* {{Fainting}}: Klara collpases when she learns that Mr. Kralik is now managing the store.
* FoodPorn: When Mr, Matuschek invites errand boy Rudy to share Christmas dinner with him:
-->'''Matuschek''': Rudy, do you like chicken noodle soup?
-->'''Rudy''': I certainly do, Mr. Matuschek.
-->'''Matuschek''': And what would you think of roast goose stuffed with baked apples, and fresh boiled potatoes in butter, and some red cabbage on the side, huh?
-->'''Rudy''': I'd love it!
-->'''Matuschek''': And then some cucumber salad with sour cream...
-->'''Rudy''': Oh, Mr. Matuschek!
* FourthDateMarriage: Back then it didn't seem hard to imagine becoming engaged over the weekend to a man you have never even met face-to-face.
* GoldDigger: Mr. Vadas, who is bleeding Mrs. Matuschek (and thus her husband) for money and favors.
* HeWhoMustNotBeSeen: Mrs. Matuschek.
* HiddenDepths: Kralik is brusque and businesslike, and Miss Novak can be blunt, but they're both deeply sensitive people underneath their exteriors.
* HotAndCold: Miss Novak to Kralik. One of the most well known early examples in fiction (Type 2 to be exact), [[LampshadeHanging Lampshaded]] when she said she read a book that tells her that if you [[KickTheDog treat a man like a dog]] he'll be eating out of your hand but all he did [[TheDogBitesBack was return the favor]].
* InsistentTerminology: [[LampshadeHanging Lampshaded]]:
-->'''Pepi:''' I'm a contact man. I keep contact between Matuschek & Co and the customers - on a bicycle.
-->'''Doctor:''' You mean an errand boy.
-->'''Pepi:''' Doctor, did I call you a pill-peddler?
* InternalReveal: When Miss Novak finally finds out who her Dear Friend is.
* InterruptedSuicide: Mr. Matuschek with a gun (interrupted by Pepi) when he finds out his wife has been [[MistakenForCheating cheating on him with Mr. Vadas instead of Mr. Kralik (as he originally suspected)]]. He does it not so much because of the infidelity itself, but because he feels guilty about suspecting Kralik in the first place, and firing him. Though when he returns from the hospital, the bittersweet pain in his eyes at being welcomed "Home" by his employees shows that he knows that the workplace has become more of a home to him than his actual house.
* LastNameBasis: The shop workers all address each other as "Mr. _____" or "Miss _____". Kralik does start privately calling Miss Novak "Klara" once he begins to care for her, though.
* LivingWithTheVillain
* LoveBeforeFirstSight: The two leads fall in love through written letters.
* MarriedToTheJob: Mr. Matuschek.
* MeanBoss: Mr. Matuschek crosses into this a little bit through the early part of the movie, although he undergoes something of a HeelFaceTurn after surviving his suicide attempt, winding up as something almost like a TeamDad.
* MistakenForCheating: Inverted; Mr. Matuschek knows that his wife is cheating with one of his employees and comes to the conclusion that it is Mr. Kralik. It's really Mr. Vadas.
* JerkAss: Vadas, and to a lesser extent Pepi.
* SayMyName: How many times was the name Matuschek uttered in the film?
* ShapedLikeItself: Why Miss Novak likes the music box.
-->'''Miss Novak''': Well, cigarettes and music, I don't know. It makes me think of moonlight. And cigarettes. And music.
* SmugSnake: Vadas.
* StoodUp: Kralik didn't intend to stand Miss Novak up--but he loses his job. And then she's particularly cruel to him at the restaurant after he comes in and sits at her table. So he goes home without revealing himself. Miss Novak takes being Stood Up very badly.
* TechnoBabble:
-->'''Doctor:''' It appears to be an acute epileptoid manifestation and a pan phobic melancholiac with indication of a neurasthenia cords.
-->'''Pepi:''' Is that more expensive than a nervous breakdown?
* TheThirties: Technically from 1940, but the feeling is much more Depression-era '30s than WWII-era '40s: Matuschek worries about money, Miss Novak desperately needs a job, and Kralik is less than overjoyed by the prospect of having to look for another one. (The play on which it was based premiered in 1937.)
* TranslationConvention: They live in Hungary, after all.
* TrueCompanions: Mr. Matuschek says that Kralik is [[LikeASonToMe like a son to him]]. Also, he takes the new delivery boy home for Christmas Eve dinner after discovering that both of them are spending the holiday alone.

* XanatosSpeedChess: How Miss Novak manages to get a job with Matuschek. She sees a customer examining the cigarette box and pretends to be a clerk, commenting that it's a lovely box. The customer asks if it's a candy box, and Miss Novak, seeing that the customer wants it to be one, says that it is. She then opens it, demonstrating that it plays a tune. The customer thinks that this is a terrible idea. ("Imagine, every time you take a piece of candy, you have to listen to that song.") Miss Novak agrees, but says that that's precisely what's ''good'' about it; noticing that the customer herself is a bit overweight, she says "There's no denying that we all have a weakness for candy" and explains that they designed the box in such a way that it plays a tune to remind you that you're about to eat yet another piece ("This little box makes you candy-conscious.") The customer asks how much it is, and Miss Novak quotes her a price which is more than they were planning to sell it at, adding that it's reduced from twice as much again. The customer buys it. Miss Novak gets hired.
